QCD two-loop amplitudes for e+e- --> 3 jets: the fermionic contribution
S. Moch, P. Uwer, S. Weinzierl
We review a new technique for the calculation of two-loop amplitudes and discuss as an example the fermionic contributions to e+ e- --> q qbar g.
Space/Time Noncommutativity in String Theories without Background Electric Field
G. De Risi, G. Grignani, M. Orselli
The appearance of space/time non-commutativity in theories of open strings with a constant non-diagonal background metric is considered. We show that, even if the space-time coordi…
Unquenched Numerical Stochastic Perturbation Theory
F. Di Renzo, V. Miccio, L. Scorzato
The inclusion of fermionic loops contribution in Numerical Stochastic Perturbation Theory (NSPT) has a nice feature: it does not cost so much (provided only that an FFT can be impl…
Soft-Gluon Resummation for Bottom Fragmentation in Top Quark Decay
Matteo Cacciari, Gennaro Corcella, Alexander D. Mitov
We study soft-gluon radiation in top quark decay within the framework of perturbative fragmentation functions. We present results for the b-quark energy distribution, accounting fo…
O(D) invariant tachyon condensates in the 1/D expansion
G. Grignani, M. Laidlaw, M. Orselli +1
We consider the problem of condensation of open string tachyon fields which have an O(D) symmetric profile. This problem is described by a boundary conformal field theory with D sc…
Boundary One-Point Functions, Scattering, and Background Vacuum Solutions in Toda Theories
V. A. Fateev, E. Onofri
The parametric families of integrable boundary affine Toda theories are considered. We calculate boundary one-point functions and propose boundary S-matrices in these theories. We…
The fully differential single-top-quark cross section in next-to-leading order QCD
B. W. Harris, E. Laenen, L. Phaf +2
We present a new next-to-leading order calculation for fully differential single-top-quark final states. The calculation is performed using phase space slicing and dipole subtracti…
Two-loop amplitudes with nested sums: Fermionic contributions to e+ e- --> q qbar g
Sven Moch, Peter Uwer, Stefan Weinzierl
We present the calculation of the nf-contributions to the two-loop amplitude for e+ e- --> q qbar g and give results for the full one-loop amplitude to order eps^2 in the dimension…
Is There a Significant Excess in Bottom Hadroproduction at the Tevatron?
M. Cacciari, P. Nason
We discuss the excess in the hadroproduction of B mesons at the Tevatron. We show that an accurate use of up-to-date information on the B fragmentation function reduces the observe…
Boundary One-Point Functions, Scattering Theory and Vacuum Solutions in Integrable Systems
V. A. Fateev, E. Onofri
Integrable boundary Toda theories are considered. We use boundary one-point functions and boundary scattering theory to construct the explicit solutions corresponding to classical…
Fast evolution of parton distributions
Stefan Weinzierl
I report on a numerical program for the evolution of parton distributions. The program uses the Mellin-transform method with an optimized contour. Due to this optimized contour the…
Symbolic Expansion of Transcendental Functions
Stefan Weinzierl
Higher transcendental function occur frequently in the calculation of Feynman integrals in quantum field theory. Their expansion in a small parameter is a non-trivial task. We repo…
Scanning of the e+e- to pi+pi- cross--section below 1 GeV by radiative events with untagged photon
V. A. Khoze, M. I. Konchatnij, N. P. Merenkov +3
We discuss an inclusive approach to the measurement of the e+e- --> pi+ pi- cross--section by the radiative return method without photon tagging. The essential part of this approac…
